Earl E. Galusha, Salt Lake City, Utah, assignor, by direct and mesne assignments, of two-fifths to William Fotes andone-fifth to Horace '0. Beck, both of Salt Lake City,'Utah Application October 12, 19 50, Serial"No.- isas'o's This invention relates core cleaners;

-.' -An object of this invention is to provide an improved structural assembly for retaining and cleaning a. filter :core,- preferably of the type whichis used in diesel engine fuel systems. p v Another object of this invention is to provide the entirecleaning assembly on the top or cover of a tank, the tank being adapted to contain a cleaning fluid of standard type, which cleaning fluid-is drawn by; means of a gearpump into a to improvements in filter r pressure chamber, thepressure chamber having 5 communication with the interior of a filter core which-is arranged in a core chamber, whereby the cleaning fluid after having served its purpose in connection with the core is permitted to drop through adrain'into the tank.

Another object of this invention is to provide arm-improved means of retaining the filter core on thespindle of the device.

Ancillary objects and features ofdmportance will'become apparent in following thedescrip'tion or the illustrated'form of the invention.

"Figure -Bis a sectional view taken substantially along the line 6-6 of Figure 2 and in thedirection-of the arrows-showing primarily the carrier bearing for the standard oil filter core.

"In carrying out this invention I have provideda ing all of the operative elements located directly 1 on the tank 10, for example on the mounting {plate 24- of the cover 15, there need not be any separation of anyof the parts and need not be any special supports other than those which are connected directly with the tank [0.

An mators-Sis used to-operatethe gear pump; the gear pump :being of standard description including the driving shaft as well asthe spindle 32, the shaft 3p and the spindle l3 2Z'supporting the gears 34 and 36 of thepump noted from inspection of Figure 5 the gear}! is keyed as at 38 to the shaft ifll and the'gears I31 and 36 arelocated in the casingor pump-hous ing ML- The shaft 30 is connected to the motor shaft by means of a standardcoupling and hence; upon operation of the motor 26 the gear pumpfa) becomes operative. A conduitgenerally indicated at 46 extendsifrom within the tank .H) to the gear pump 28 and then from the gear pump 28 into the pressure chamber 48. I This'pressure chamber is defined by a casing 50 which may be a casting with a removable end plate 52 thereonIQ-This pressure chamber is adapted to receive vfluid under pressure through the conduit lfi and to allow that fluid to be passedinto the filteroore 22. -As disclosed in Figure )2 theshaft iii-passes through standard oil seals 49 and 5| OIl-ODPOSltB sides of the gear pump28 and the shaft has a carrier bearing 54 keyed thereto.- This carrier arm in order to seat another ,part of the filter ,22,

There is aring at the cuter ends of thearms 56-integrally connecting them-and this .ring constitutes a'beari ng whichisdisposed in a central opening or aperture 62 in thevertical partition nltercorechamber' and a:small outlet pipe :12

is connected therewith and opensinto .a'zchamber H defined'by the portion 713 in'the'tank L0. :The chamber H hasa filter .15 therein through which the cleaning fluid must :flow since the pipe]! extends a considerable'distance .into :it.- The outlet member 1.1 for the filtered fluid :is located in the partition 13 and-is arranged to :conduct the filtered fluid .fromthe chamber]! intoithe remainder of the-tank I D. l

In order to hold the filter core 224m the pi'ndle T4 in the core-chamber 66,-"an improved centering device is 'used. A standard oil seal 18 is .con-

nected to the removable closure of the casing 50 'andfihas a shank 82 mounted for rotation therein; There is a tapered end 84 o'n this'spindle-arranged to be disposed in the centraliopeningBB of the co'llar88. collar-is threaded on its-outer periphery to accommodate the nut 90, thefunction of the nut being to abut the posed-in a threaded bore of the spindle- 82,

OFFICE pered end 84 is pulled firmly in the central aper ture 86 of the collar 88. This holds the filter core I 22 fixed firmly around the spindle "which is in fact, an extension of the shaft 36.

In operation the motor 26 is set in motion after a core has been inserted through the opening of the casing 56 and held in place'through' the ex pedient of the tapered end 84 on the spindle or shank 82. Inasmuch as'operation of the motor 26 causes the gear pump-28 to be operative, fluid is'raisedfrom the tank 16 and introduced under pressure into the "pressure' chamber 48. This fluid'has no placetodischarge except between the arms '56 of the carrier bearing 54. 133 passing into'the inner sleeve" of thecore 22und'er pressure,'t he fluid passes through allof the openings, screens and the like of the filter core while it is being rotated on the spindlelL- In order to break the flow of fiuid in the core chamber 66 and in order to cause a swirling action of the liquid, the baifies 98 which are located longitudinally within the core chamber 66 deflect the fluid appropriately and properly.

-Ifhen the fluid after it has served its purpose in the core chamber' '66 is discharged into the chamber H of the tank (6 through the sump I0 and the outlet member 12. I When it is necessary to draw the top fiuid from the tank I, the valve [4 is used. When it necessary to remove the sediment-or clean the tank, the plug I 2 is used. I a Having described the invention, what is claimed as new isr' l lLIn a filter core cleaner, a liquid tank havinga topand means disposed on said top for chamber, a filter core end carrier'bearing having' liquid passages therein connected to. said pump outlet,said bearing being fixed to said, shaft,- and meansf'or supporting the other end of the filter core. r v.
